Molecular tuning of excitons and polarization anisotropy in hybrid bilayer crystals

Posted by dbos December 16, 2024January 7, 2025Berkeley, This Week: Nanoscience

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Tomojit Chowdhury, Aurélie Champagne, Fauzia Mujid, Patrick Knüppel, Zehra Naqvi | Summary: Bilayer crystals, built from monolayers of two-dimensional (2D) crystals with different lattice orientations, generate interlayer potentials leading to unique excitonic properties. However, the ability to tune the interlayer potential is limited by the fixed […]

Vortex-Induced Rings and Gaps within Protoplanetary Disks

Posted by dbos December 16, 2024January 7, 2025Peking, This Week: Astrophysics

Kavli Affiliate: Ruobing Dong | First 5 Authors: Xiaoyi Ma, Pinghui Huang, Cong Yu, Ruobing Dong, | Summary: Observations of protoplanetary disks have revealed the presence of both crescent-shaped and ring-like structures in dust continuum emission. These crescents are thought to arise from dust-trapping vortices generated by the Rossby Wave Instability (RWI), which induces density […]

X-ray properties of coronal emission in radio quiet Active Galactic Nuclei

Posted by dbos December 15, 2024January 7, 2025Peking, This Week: Astrophysics

Kavli Affiliate: Claudio Ricci | First 5 Authors: Sibasish Laha, Claudio Ricci, John C. Mather, Ehud Behar, Luigi C. Gallo | Summary: Active galactic nuclei (AGN) are powerful sources of panchromatic radiation. All AGN emit in X-rays, contributing around $sim 5-10%$ of the AGN bolometric luminosity. The X-ray emitting region, popularly known as the corona, […]

Detecting the Coupling of Axion Dark Matter to Neutron Spins at Spallation Sources via Rabi Oscillation

Posted by dbos December 14, 2024January 7, 2025This Week: Astrophysics, Tokyo

Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Peter Fierlinger, Jie Sheng, Yevgeny V. Stadnik, Chuan-Yang Xing, | Summary: We propose a novel detection method for axion dark matter using the Rabi oscillation of neutron spins in beam-based measurements. If axions couple to neutron spins, a background oscillating axion dark matter field would drive […]

Floquet-Thermalization via Instantons near Dynamical Freezing

Posted by dbos December 13, 2024January 7, 2025Cornell, This Week: Nanoscience

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Rohit Mukherjee, Haoyu Guo, Debanjan Chowdhury, , | Summary: Periodically driven Floquet quantum many-body systems have revealed new insights into the rich interplay of thermalization, and growth of entanglement. The phenomenology of dynamical freezing, whereby a translationally invariant many-body system exhibits emergent conservation laws and a slow […]

Real-Time Simulation of Asymmetry Generation in Fermion-Bubble Collisions

Posted by dbos December 13, 2024January 7, 2025Chicago, This Week: Astrophysics

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Ying-Ying Li, Tong Ou, Hersh Singh, | Summary: We perform real-time simulation of fermion-bubble scattering during a first order phase transition by which the fermions become massive. This out-of-equilibrium dynamics can generate a CP asymmetry, which is a crucial ingredient for baryon asymmetry generation in […]

T-GMSI: A transformer-based generative model for spatial interpolation under sparse measurements

Posted by dbos December 13, 2024January 7, 2025Cornell, This Week: Nanoscience

Kavli Affiliate: Jie Shan | First 5 Authors: Xiangxi Tian, Jie Shan, , , | Summary: Generating continuous environmental models from sparsely sampled data is a critical challenge in spatial modeling, particularly for topography. Traditional spatial interpolation methods often struggle with handling sparse measurements. To address this, we propose a Transformer-based Generative Model for Spatial […]

Selective Targeting of a Defined Subpopulation of Corticospinal Neurons using a Novel Klhl14-Cre Mouse Line Enables Molecular and Anatomical Investigations through Development into Maturity

Posted by dbos December 12, 2024January 7, 2025This Week: Neuroscience, UCSD / Salk

Kavli Affiliate: Eiman Azim | Authors: Jake Lustig, Alexander Lammers, Julia Kaiser, Payal Patel, Aidan Raghu, James M. Conner, Phong Nguyen, Eiman Azim and Vibhu Sahni | Summary: The corticospinal tract (CST) facilitates skilled, precise movements, which necessitates that subcerebral projection neurons (SCPN) establish segmentally specific connectivity with brainstem and spinal circuits. Developmental molecular delineation […]
